Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. It took us a long time to get the data needed to let us connect to the grid.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. grid, but the rising number of EVs will test the local grid’s reliability at many of the 3,000 electric-distribution utilities in the United States , which themselves own more than 5.5

ORNL licenses high-power wireless vehicle charging technology to HEVO

Green Car Congress

The license also includes ORNL’s Oak Ridge Converter, which eliminates one of the power conversion stages needed for wireless power transfer, resulting in more compact and less costly stationary infrastructure. It directly converts 60-hertz AC power from the grid to high-frequency AC without taking an intermediary conversion to DC power.
